Yes. As of 7/1/2014, with LEED Interpretation #10388, the environmental tobacco smoke (ETS) prerequisite applies to e-cigarettes as well as conventional cigarettes. USGBC cites the World Health Organization, stating that "e-cigarettes should be prohibited anywhere where the use of conventional cigarettes is prohibited." The interpretation also updated the definition of smoke to include “smoke produced from the combustion of cannabis and controlled substances and the vapors produced by electronic smoking devices."
